How to make RDP not log out after a while?

Question

RDP

Given:
Several working computers, without admin rights with strict group policies, connecting to them via RDP
Sometimes you work in one of them, while others log out at this time.
When switching after 20-30 minutes, you constantly need to enter the password, it's annoying

How to do to keep the RDP connection active automatically? Maybe there are some clickers?
There are no access to group policies, etc. on those machines

Answer 1

Remove splash screen on target machine

Answer 2

create shortcuts with ready-made logins/passwords...

Answer 3

Ask admins about session timeouts ... let them specifically correct the policies for the listed computers
Well, or your Wishlist does not fit into the requirements of the organization's security policy
